Quantum Dots and Ultra-Efficient Solar Cells?

The efficiency of solar cells is the electrical power it puts out as percentage of the power in incident sunlight. One of the most fundamental limitations on the efficiency of a solar cell is the ‘band gap’ of the semi-conducting material used in conventional solar cells: the energy required to boost an electron from the bound valence band into the mobile conduction band. When an electron is knocked loose from the valence band, it goes into the conduction band as a negative charge, leaving behind a ‘hole’ of positive charge. Both electron and hole can migrate through the semi-conducting material.
